Your daughter makes use of those art classes she took as a child and becomes an artist.
Well, that's okay...To each her own.
Intelligence = Less than 299
Art = At least 80
If you give her a good sensitivity, she will do even better as an artist!
Taking a lot of art classes and regularly attending the Art Festival increase the chances of getting the Artist ending. If she gets her art skill mostly from dancing, she will most likey become a Dancer instead. High intelligence will often make her a Writer.
It is a long-perpetuated myth that having the Master Brush (prize for winning the Art Festival) secretly locks you with the Artist, Dancer or Writer ending. It does not. In fact, the artistic endings supersede the other endings only if your art rating is higher than your combat attack or magic attack rating (in other words, the brush does not do it, the art rating given by the brush does it.) You can end the game with the Master Brush and still achieve Grand Poobah, General, Court Magician or any other high ending if your combat or magic attack are higher than your Art. It is actually easier and less wasteful to achieve a high social reputation by keeping the Master Brush than by working the bar for Conversation. The easiest way to get an attack higher than your Art with the Master Brush is to max your Magic Attack through Fay blessings and visit the elf in the forest.
